JOHN A. ANDERSON, OF COUNCIL BLUFFS, IOWA.

TRUSS and State of Iowa, have invented certain new and usefulImprovements in Trusses, of which the following is a specification,referones being had to the accompanying drawlngs.

My invention relates to improvements in trusses, and consists of thenovel features of construction and the combination and arrangement ofparts hereinafter fully described and claimed.

The object of the invention is to provide a truss of improvedconstruction which may be easily adjusted and held in position withoutthe use of a spring and without discomfort to the wearer.

The above and other objects of the invention are attained in itspreferred embodiment illustrated in the accompanying drawing, in whichFigure 1 is a perspective view of my improved truss; Fig. 2 is avertical sectional View taken on the plane indicated by the line 22 inFig. 1 and Figs. 3 and 4 are detail horizontal sectional views taken onthe planes indicated by the lines 33 and 4--4 in Fig.

In the drawings 1 denotes a supporting plate or member which carries anadj ustably mounted truss pad 2 and is adapted to be held in positionupon the body of the wearer by a body strap 3 and a thigh or leg strap4.

The support 1 is preferably made of a piece of heavy leather or othermaterial having very little flexibility; and it has a reduced lowerportion 5 separated from its upper por tion 6 by one or more grooves orscores 7 so that the two parts 5, 6 may bend with respect to each otherwhen the wearer stoops over. The body strap 3 has an adjusting buckle 8at one end and said end is suitably secured upon the outer face of'theupper part 6 of the support adjacent to the top of the latter. The thighstra 4 is also provided with an adjusting buck e 9 and is similarlysecured upon the lower part 5 of the support 1. If desired, the innerface of the support 1 may be covered with lining 10 of flannel or othersoft fabric which is cemented or otherwise suitably secured.

The truss pad 2 consists of a core or button 11 having a convex outerface and a recessed Specification of Letters Patent.

' inner face. The outer face of the core 11 is edges of which coverings12, 13 are secured in the recess in the inner face of the core by aremovable clamping plate 14, as clearly shown in Fig. 2. The pad 2 isvertically adj ustable upon the support 1 by forming in the latter aseries of apertures 15 to receive a screw 16 having its head 17 securedagainst rotation in the core 11 beneath the plate 14 and its screwthreaded end 18 engaged by a milled nut 19. By making the support 1comparatively long and of flexibly or hingedly connected lower and uppernon-flexible portions or sections 5, 6 and by providing the body strapupon the upper section 6 and the thigh strap upon the lower section 5,it will be seen that the device will be effectively held in positionupon the wearer without the use of a spring or s rings, and that therewill be little or no liabi ity of the device shifting out of its properposition. Thescoring of the leather support 1 allows its two ortions orsections to swing or fold to angu ar positions when the wearer bends orstoops, thus insuring comfort to the wearer. The two attaching strapsenable the device to be easily applied, adjusted, and removed, and theadjustment of the pad permits the latter to be held at the proper placeupon the body. It will be understood that the trusses may be constructedfor use upon either side of the body, and that they may also be madedouble.

Having thus described my invention what I claim is:

1. A truss comprising a substantially rigid supporting plate scored orgrooved to divide it into upper and lower portions adapted to bend uponeach other, a pad upon the upper portion, and an attaching strap uponeach of said portions.

2. A truss comprising a support, attaching straps thereon, a pad havinga core the core, a clamping plate secured u on the recessed face of thecore for clamping the edges of its covering in the recess, and means forattaching the pad to said support.

3. A truss comprising a support, attaching straps thereon, a pad havinga core formed with a recessed face, a covering upon the core, a clampingplate secured upon the recessed face of the core for clamping the edgesof its covering in the recess, a screw covered with leather 12 andflannel 13, the.

formed with a recessed face, a covering upon having its head securedagainst rotation in the core beneath said clamping plate, the threadedend of the screw being adapted to be passed through one of a pluralityof apertures formed in the support, and a nut upon the threaded end ofthe screw.

4. A truss comprising a substantially rigid supporting member scored orgrooved to divide it into upper and lower portions adapted to bend uponeach other, a pad upon one portion and an attaching means upon each ofsaid portions.

5. A truss comprising a support formed with a series of openings, a padhaving a screw stud projecting from it and adapted to be passed throughone of the openings in the support to adjustably position it thereon, anut upon the projecting threaded end of the screw stud, an adjustablebody strap secured to the upper portion of said support and anadjustable leg or thigh strap secured to the lower portion of saidsupport.

6. A truss comprising a supporting plate or member having flexiblyunited upper and lower portions, the upper portion being formed with aseries of apertures, a pad having a screw stud projecting through one ofsaid apertures, a nut upon the projecting threaded end of said stud, anadjustable body strap attached to the upper portion of said plate ormember and a leg or thigh strap attached to the lower portion of saidplate or member.

In testimony whereof I hereunto aifix my signature in the presence oftwo witnesses.
